El Mercurio spoke to Chilean doctor Pedro Onate, who claimed that the star has suffered a medial ligament injury in his right knee but should be fit in time for Chile's attempt to win the Copa America in Brazil this summer.

The report said: “There’s no problem for Alexis playing in the Copa America because he’ll be out for between six and eight weeks.

“A medial ligament injury is annoying but not as complex.”

Sanchez has only managed 23 appearances for the Red Devils this season and has been started just eight times in the Premier League.
